    Note that dynamic IP means that you must register your current IP with a machine with static IP somewhere. Look at dyndns.com for example.

    But there is another problem. Dynamic IP may also imply that the module is firewalled so that it does not accept incomming connections, even if you know the IP. Because of this, you may have to do the actual data transfers too trhrough a third machine, so that both the modules performs outgoing connections to the common machine.
